more tests
[maven-release-plugin] prepare release groovy-sandbox-1.1
[maven-release-plugin] prepare for next development iteration
updated the version
Fixed issue #2

Looks like Groovy is failing to handle var arg correctly if the actual
arguments that match the vararg is a single null value.

Instead of creating [null], it just passes in null.
method arguments weren't transformed correctly in a recursive manner
Should intercept property lookup
[maven-release-plugin] prepare release groovy-sandbox-1.2
[maven-release-plugin] prepare for next development iteration
test case that came from https://github.com/kohsuke/groovy-sandbox/issues/4
Fixed issue #4: static calls weren't routed properly
Changed the recorder format to differentiate static methods call vs instance call.
Bumping up GMaven to the one that supports 1.8
intercept method pointer expressions correctly
